Balance inventory, shipping zones, and priority orders with weighted allocation logic for faster fulfillment decisions. Plan smarter fulfillment with clear warehouse allocation outputs today.
Use this sample data to verify calculations and exports.
| Warehouse | Stock | Unit Cost | Distance (km) | ETA (days) | Zone Match | Fixed Fee |
|---|---|---|---|---|---|---|
| Karachi DC | 120 | 2.40 | 18 | 2 | Yes | 8.00 |
| Lahore DC | 90 | 2.10 | 28 | 3 | Yes | 7.50 |
| Islamabad DC | 150 | 2.70 | 36 | 1 | No | 6.00 |
This tool ranks each warehouse using normalized scores, then allocates units by weighted priority and available stock.
Weighted Score = (Wc×CostScore) + (Wd×DistanceScore) + (Ws×StockScore) + (Wp×SpeedScore) + ZoneBonus
CostScore = (MaxCost - Cost) / (MaxCost - MinCost)
DistanceScore = (MaxDistance - Distance) / (MaxDistance - MinDistance)
StockScore = Stock / MaxStock
SpeedScore = (MaxSpeed - SpeedDays) / (MaxSpeed - MinSpeed)
Warehouse Share = WarehouseWeightedScore / SumOfAllWeightedScores
Initial Allocation = floor(OrderQty × Warehouse Share)
Final Allocation adjusts by stock and split limits.
Weights are auto-normalized, so any numeric mix works (for example 35, 25, 25, 15).
Fulfillment allocation affects margin, speed, and customer satisfaction at the same time. Choosing a warehouse only by distance can increase handling fees or create inventory imbalances. This calculator brings those tradeoffs into one decision view using weighted inputs. Teams can evaluate cost, stock depth, and service performance before releasing an order. That creates a repeatable process, reduces manual judgment, improves consistency, and supports faster daily decision cycles across busy operations teams everywhere.
The scoring engine normalizes each warehouse metric before applying your selected weights. Normalization is important because shipping cost, distance, and available stock use different scales. Without normalization, one field could dominate the result unfairly. Increase cost weight when margin protection is the priority. Increase speed and distance weights when delivery commitments matter most. Increase stock weight when you need to balance inventory drawdown across locations during demand spikes and seasonal campaigns carefully.
Split shipment controls add practical governance for real ecommerce operations. Allowing splits can improve fill rate during constrained inventory periods, but every additional node adds labor, packaging, and coordination effort. This tool supports both strategies through the split toggle and maximum split limit. Teams can compare single-warehouse routing against multi-warehouse routing and immediately see the effect on total cost, average arrival days, and warehouse utilization within one result review for operational planners.
The output table is designed for operations, finance, and service teams. Each selected warehouse row shows score, allocated quantity, unit shipping cost, distance, delivery days, and fixed handling fee. This structure makes allocation decisions easy to audit and explain. During peak periods, managers can prioritize faster warehouses. During margin pressure, analysts can test lower-cost routes. The export options also support reporting, reconciliation, and review meetings with internal stakeholders and partners across departments.
For best results, keep warehouse inputs current and review weights regularly. Shipping costs, service times, and stock levels change quickly during promotions, seasonality shifts, and carrier disruptions. Exported outputs should be compared with actual shipment outcomes to refine assumptions. If one warehouse is selected too often, rebalance weights or inventory placement. With ongoing review, the calculator becomes a strong decision aid for scalable fulfillment planning and measurable performance improvement over time organizationwide.
It represents each warehouse’s suitability for the order based on normalized cost, distance, stock, and speed values, plus a small zone-match bonus when enabled.
Yes. Disable split shipments and the calculator will only assign the order to one warehouse with enough stock. It warns you if none can fulfill alone.
Normalization converts your weights into proportions. This keeps the ranking stable and comparable even if you enter values like 35, 25, 25, and 15.
Total cost includes variable shipping cost per allocated unit and each selected warehouse’s fixed fulfillment fee. Both are summarized in the result table.
Choose weights based on your current objective: margin control, faster delivery, or inventory balancing. Test scenarios and compare cost, splits, and average arrival.
Yes. After generating results, use the CSV or PDF buttons to export the allocation table for reviews, audits, or operational reporting.
